Specification oi Letters Patent. Patented Sept, 20 1910,

Application filed June 17, 1909. Serial. No. 502,757.

To all whom it may concern;

Be it known that I, LEONARD A. YOUNG, a

citizen of the United States, residing at Deof reference marked .thereon,1which form. a

part of this specification.

, This invention relates to a seat base construction for spring cushion seats, especially designed for railway coaches, and .conslstsin Y the construction and arrangement OffPiLItS' hereinafter more fully pointed' out and claimed.

The primary object-of the invention is to provide a seat base construction wherein the arrangementis such as to obviate the noise incident to ,seat constructions asIcommonly made, caused by contact 'ofthecoilsof the springs, when collapsed, with the H spring supporting portion of the base.

A further object is to proud for mount- ,ing in the base marginal strips-ofwood to afiord means for attaching the upholstery and to protect said strips from fire.

A further object is to provide a durable,

strong, and compact base constructionfor spring cushion seats'possessing advantageous mechanical arrangements, as will be more fully pointed out in the claims.

, The above objects are attained by the structure illustrated 'in the accompanying drawings, in which Figure 1 is an inverted plan view of a seat base construction involving my invention. Fig. "2 is a front elevation. Fig. 3 is an enlarged c oss section through one of the margins of tie base. Fig. 4 is an enlarged sec-' tional view at right angles to Fig. 3, or as taken on line 1:4'01 Fig. 10., Fig. 51s a cross section through the-structure as on line 55 of Fig. 2. Fig. 6 is afragmentary View in section online 6.-6 of Fig. Fig. 7 is a cross section through one of the bars of the frame. Fig. 8 is a detail in section through two of the stress bars of the-base,'.sl 1owing' a clip connecting said bars and a spring mounted thereon. Fig.9 is a fragmentary view in perspective of two of said bars coupled by a clip plate. Fig. 10 is a fragmentary view in top lanet 2. portion'of thebase construction, showing the clamping prongs on the ends of the posts projecting from said base between which thelcoil of the spring is confined; Fig. 11 is a similar View showing the end portions ofthe prongs bent over as when clamping the coil of the spring.

Fig. 12 is a fragmentary view in elevation of one of said posts, showing the coil of a spring lying between the prongs thereof.-

Fig. 13 is a similar view showing the endof one of the prongs bent over to confine the spring.

The marginal portion of the base of the seat .frame comprises side bars 1 and end. bars 2 which are'cast of iron and annealed and suitably joined at. their ends to form a rectangular frame. -These marginal bars at intervals are provided with short upwardly extending posts 3. arranged in pairs and the posts of each pair separated a distance equal to the diameter of the bottom coil of the border springs 4. Each post at the top I thereof is provided with upwardlyprojecting fingers 5 located at the opposite mar ins of the post on one 'side thereof, and wig a central finger 6 located on the opposite side of the post from the fingers 5 and midway between them. l, The fingers'fi'are disposed in a curved plane concentric with the circle described by the bottom coil of the springs,

and the border springs are mounted upon the posts 3 by placing the bottom coils thereof between the fingers 5 and 6 of each pair of posts, as shown. The fingers 5 are longer than the fingers 6 and tapered,'as shown in Fig. 12. To secure the springs upon the posts 3 after inserting the bottom ,coils thereof between said fingers, the tapered ends of the fingers 5' are bent inwardly onto the bottom coilof the springs, as shown in Fig. 13, thereby firmly locking .the springs to said posts. The upper ends of the border springs 4 are connected to the top border wire 7 by suitable clips 8 which embrace said wire and the top coil of said springs. The tops of the border springs are connected together by means of the interposed plates 9 shown more, clearly in Fig. 6, which are provided on their inner corners with clips that embrace thej top' coils of said springs, of said plates having at its outer edg7e a clip 1l which embraces the border wlre These plates 9 not only serve to tie the tops of the border springs together, but also afiord rneans for attaching the upholstery over the tops of the springs through the apertures 12 in said plates in a manner I which need not be explained, as it forms no bygthe' depending fingers 18 at the outer partof this invention. To enable the upolsteryjto be drawn down and secured at the under side of the base, tl16 S1de bars 1 are rovided with marginal strl s of wood 13-w ichlie behind the margina flanges 14 of said bars, said strips belng confined in place "by the fingers 15, shownmore clearly in Fig. 3, which at their outer ends are bent inwardly against said strips. For a like purpose the-end bars 2 of the base are provided with marginal strips of wood 16 which lie against the longitudinal flanges 17 of the end bars andarelconfined thereagainst *The springs 19 of the seat intermediate the border s ringsar'e supported by Sthe transverse re s 20 whose ends are provided *With a hookj2l adapted to engage in aper tures in the side bars, whereby said rods are supported in .place, as shown in Fig. 3. Said rods 20 cross the frame in pairs and are tied together at intervals by means of the clip "plates 22 which are provided at their ends with the. marginal prongs 23 that engage the inner sides of said rods and with the central pron s 24 which pass around the rods and hold'lhem against said prongs, thereby coupling the rods together, as clearly the p a ing the lower-ends of the sprin s 19, as shown-in Fig. 8 The upper en s of the springs-19am connected to one another and to the bordersprings by suitable. clips 26. The supporting rods 20are dropped below the lane of"v the side bars of the frame, whtijebya greater depth of spring is afford: ed in the'center of the seat.

By reason of the fact, that the. border springs are mounted upon the posts 3 of the marginal base bars of the frame, said springs are" held above. said. bars in such manner asto prevent the coils thereof comingin contact with the bars when said coils are depressed by a weight upon the cushion,

, pbv'iatmgfthe liability of any clicking sound 'teningxsaid coils to said posts.

shownv in Fig. 9. In'the center of tes 22 is-an aperture ,25for attach-- the coils of the spring with. the marginal [by reason of the occasional engagement of bars of the base, as occurs in seat construe-- tions in common use.

-Having thus fully set forth my invention,

what I claim as new and desire to secure by Letters Patent, is

' 1. A base constructlon for spring seats comprising marginal bar's having relatively small oppositely disposed posts extending above the plane thereof, border springs mounted upon the-upper ends of said posts which engage opposite marginal portions of the bottom coils thereof, and means for fas spring seat structure comprising a lower frame, an upper border wire, border springs connected at their upper ends to said border wire, and means engaging marginal portions only of the lower coils of,said springs for supporting the lower ends thereof above the plane of thebase frame and free from contact therewith.

3; In a sprin seat structure, a base frame,

an upper bor er -wire, centrally disposed.

border wire, and means upon the marginal portions only of the base frame enga 1n sectoral portions only of the bottom coi s 0 said sprlngs for supporting the lower ends of the border springs above the plane of said base and free from contact therewith.

4:- A base construction for spring seats, comprising a frame having marginal bars, side bars having posts rising vertically therefrom arranged in pairs, fin are upon the upper ends of said posts,*and order springs mounted upon said-posts and engaged by said fingers to retain them thereon.

comprising marginal bars, posts projecting vertically from said bars, border s rings each mounted upon the tops of a plura ity of said posts which engage the bottom coils of saidsprings at points only in the circumference thereof, and means for securing the springs to the upper ends of said posts'to retain them in place.

6. A base construction for spring seats, comprising marginal bars having depending marginal flanges, a filling strip of wood or analogous material lying against said flan e, and a plurality of supporting fingers pending from said marginal. bars an engagingsaid filling-strip, said fingers being bent laterally to securely hold said strip against said'flanges.
